Myself and Unitedpuppyslayer threw a couple of Ross Brandt's prototypes today. He has a much bigger cannon of an arm than I do with me being a consistant 300-315 thrower maxing around 350 and he being a 450ish thrower. Of the 2 that I threw one was pretty flippy and the other was a bit more stable than the first one I threw. They felt pretty light as we had no clue on the weights of the discs. I would compare one of them to a nuke and the other to a Bolt. The flippy one flew pretty good for me so I am most def gonna give it a try when they are released.
